Changed your phone number or want to update your linked email? You can do this in Binance's security settings. But since it involves account security, the process requires strict identity verification.
Changing Your Phone Number
Scenario 1: Old phone number still works
This is the simplest case:
- Open the Binance app → Profile → Security
- Find "Phone Verification"
- Tap "Change"
- The system sends a verification code to your old number — enter it
- Enter your new phone number
- Receive and enter the verification code for the new number
- May also need to enter email and/or Google Authenticator codes
- Confirm the change
If you don't have a Binance account yet, register on Binance with a reliable phone number from the start to avoid future hassles.
Scenario 2: Old phone number is no longer in use
This is trickier since you can't receive codes on the old number. Manual review is required:
- In security settings, tap "Change Phone Number"
- Tap "Unable to verify" or "I can't access my old number"
- The system asks you to submit a request:
- Upload photos of your ID (front and back)
- Record a video selfie (saying specific numbers or words)
- Provide account information (registration date, recent trades, etc.)
- Wait for manual review (typically 1–7 days)
- After approval, bind your new phone number
Changing Your Email
Scenario 1: Old email still accessible
- Security Settings → Email Verification → Change
- Verify old email (receive and enter code)
- Enter new email address
- Verify new email (receive and enter code)
- Enter other security verifications (phone/Google Authenticator)
- Confirm the change
Scenario 2: Old email inaccessible
Process is similar to the phone number case — submit a manual review request. Have your ID documents and account information ready.
Security Restrictions After Changes
After changing your phone number or email, Binance applies temporary security restrictions:
- Withdrawal restriction: No withdrawals for 24–48 hours after the change
- C2C restriction: C2C trading may be limited for a period
- Security setting restrictions: Can't modify other security items for a short time
These restrictions prevent hackers from changing security info and quickly transferring assets after gaining access. Inconvenient, but necessary protection.
Changing Both Phone and Email
If you need to change both, you can't do it simultaneously:
- Change one first (e.g., phone number)
- Wait for the security restriction period to end
- Then change the other (email)
If both are inaccessible, you can only go through manual support — the review will be more stringent, requiring more proof.
FAQ
Q: Does changing phone number affect Google Authenticator? No. Google Authenticator is bound independently and is unrelated to your phone number.
Q: Can I log in with the old email after changing? No. After the change, only the new email can be used to log in.
Q: Can I bind an international phone number? Yes. Binance supports phone numbers from most countries and regions worldwide. Select the correct country code.
Q: Can one phone number be bound to multiple Binance accounts? No. One phone number can only be bound to one account.
Recommendations
- Use a long-term stable phone number and email
- Bind Google Authenticator as a backup verification method
- If you know you're changing numbers, update the binding in advance
- Keep your registration information (email, phone) saved — it's needed for account recovery
- After changes, verify all security verifications are working properly
Phone number and email are the foundation of account security. The somewhat tedious change process actually demonstrates Binance's commitment to security.
